MEANS FOR SUPPLYING FUEL TO STOVES.

Application filed September 5, 1907.

To all whom it may concern:

Be it known that I, WILHELM GLENK, whose post-oflice address is No. 7 Krellerstrasse, at Nuremberg, Bavaria, Germany, have invented certain new and useful Imgrovements in Means for Supplying Fuel to toves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in fuel feeding devices adapted for use in connection' with heating or cooking stoves and also capable of use in connection with heating devices of other kinds.

The invention is primarily designed to be operated manually, although it is capable of being otherwise operated, and is arranged to receive and retain a quantity of fuel in excess of the amount to be fed at one time and to be manipulated for the purpose of delivering a portion of the retained charge to the fire bed. The arrangement is such that the charge or amount of fuel retained may be fed in successive quantities upon the fire bed and in the preferred construction means are provided for preventing movement of the fuel in a direction reverse from a feeding position.

The invention will be more fully described in connection with the accompanying drawing and will be more particularly pointed out and ascertained in and by the appended claims.

In the drawing: Figure 1 is a vertical sectional view showing the device of my invention applied to a stove. Fig. 2 is a plan view thereof showing the upper portion of the stove removed. Fig. 3 is a vertical longitudinal sectional view of a modified form of Fig. 4 is a plan view thereof. Fig. 5 illustrates the device of my invention applied to a heater. Fig. 6 is a sectional View thereof on line 66 of Fig. 5.

Like characters of reference designate similar arts throughout the different figures of t e drawing.

Referring first to the form shown in Figs. 1 and 2 a designates the grate which may be of any suitable construction and which as shown is disposed adjacent a fire or bridge wall a. The products of combustion pass from the grate a to a suitable outlet (not shown) as indicated by the arrow.

The stove plate is indicated at f and is Specification of Letters Patent.

rovided with an opening f through which fuel may be supplier A fuel receiver is indicated at c and as shown the same is movably mounted on wheels at supported in grooves d to permit saidreceiver to be reciprocated. At its rear or intake end said receiver is in proximity to the openingf to receive the fuel and said end is closed by a wall 0. At its discharge or delivery end 0* said receiver is in proximity to the grate a. According to the embodiment shown the receiver is reciprocated to effect delivery of the charge of coal contained therein to the grate a and to this end means are provided preferably in the form of a handle 6 attached to the wall 0 for manually imparting the requisite movement to said receiver. Said handle 6 ro'ects through an opening in the front wa of the stove in a manner to be accessible to the operator. Reciprocating movement of the receiver c is limited in one direction by engagement of the wall 0 with the front wall of the stove and means are provided for limiting movement in an opposite direction which means as shown consists of an abutment g, which is fixed. in place, and which lies in the path of an abutment h mounted on the receiver. After the receiver 0 is filled with a char e of fuel the operator gras s the handle c ant forces the receiver towarc the grate a, or in a feeding direction until the abutment it strikes the abutment g whereupon the receiver 0 will be suddenly brought to a position of rest. Thesudden arrest of movement will cause a portion of the charge to be delivered upon the grate a where it will be consumed in the rocess of combustion. If it is desired to deliver another portion of the charge to the fire bed the o erator will withdraw the receiver from a feeding to a nonfeeding position and will again thrust it forwardly into a feeding position whereupon the abutments will act in the manner hereinbefore set forth to deliver an additional quantity of fuel. This operation may, if occasion requires, be repeated until all of the charge or contents of the receiver has been delivered in successive quantities to the fire bed. If it is desired to deliver but one portion of the charge the receiver may be permitted to remain in a forward or receiving position which will result in freeing a portion of the gases from the fuel nearest the delivery end of the receiver, due to the intense heat to which the same is subjected, and thereby facilitating combustion of that portion of the charge when the same is subsequently delivered to the fire bed.

Under some conditions the reciprocation 5 of the receiver from feeding to non-feeding positions and vice versa would merely tend to advance the coal in opposite directions without imparting thereto a progressive feeding movement toward the delivery end of the receiver and thus there would be little or no delivery of the fuel to the grate. To avoid this defective operation means are provided tending to prevent movement of the fuel rearwardly in the receiver or toward the wall 0 when the latter is suddenly brought into engagement with the front wall of the stove and as shown said means consists in an improved construction of the walls of the receiver. As shown the receiver 0 is gradually decreased in size from the delivery to the receiving end so as to retard rearward move ment of the fuel as the result of impact of the wall 0 with the front wall of the stove and to further retard such rearward movement of the fuel, the bottom wall 0 of the receiver may if desired be inclined upwardly from the delivery to the receiving end and the lateral walls 0 converge from the delivery to the receiving ends. In the most improved embodiment of the invention the lateral or bottom or both of said walls may be off-set or stepped to provide a plurality of rearwardly facing surfaces 0 and c which serve effectively to prevent rearward move ment of the fuel. In the embodiment shown the receiver 0 is disposed within the stove and beneath the stove plate on which the lids are disposed although it will be understood that this disposition of the receiver is 40 not essential to a full realization of the advantages of the invention. However when this disposition is made it will be obvious that the fuel in the receiver may be allowed to ignite by leaving the receiver in a forward or feeding position whereby the fuel nearest the fire bed will be ignited and will very gradually and slowly ignite the remainder of the contents of the receiver. Such ignition will necessarily be slow and gradual for the reason that effective draft has been purposely omitted with respect to the receiver. Such moderate combustion has especial advantages in some kinds of cooking and as the fuel in the receiver is closely adjacent the stove plate f the heat is readily transmitted thereto. It will be understood that in this utility of the invention the fire in the grate may be allowed to die out. I consider it a feature of novelty to dispose a movable re- 6 ceiver within a stove and in such close proximity to the grate and stove plate for heating surface as to enable said receiver to perform the function hereinbefore set forth.

In the form shown in Figs. 3 and 4 the 6 grate a is shown approximately on a level with a grate extension 7c. The bottom Wall? of the receiver 0 is provided with a bar 'L which is disposed in such a manner as to be able to move abreast of the extension 7c with a slight working clearance. WVhen a portion of the charge of the receiver has been delivered to the grate and the receiver is retracted as shown in Fig. 3 the burning fuel is permitted to slide down upon the extension is and against the bar i to extend the area of the fire bed. When the receiver 0 is again advanced to a feeding position the ashes remaining on the extension is are forced forwardly on the grate and are permitted to fall therethrough. A damper m 30 may be advantageously disposed above the receiver 0 to properly deflect the products of combustion. Otherwise the operation of this modified form is in all respects similar to the operation of the form hereinbefore 5 described. The abutment limiting movement of the grate may be formed by shortening the grooves cl in which the wheels d travel so that the wheels nearest the grate will engage the ends of said grooves and arrest movement of receiver in a feeding direction.

In the form shown in Figs. 5 and 6 the construction and operation of the device of my invention is substantially the same as in the form shown in Figs. 1 and 2 except that the device is applied to a heater and the latter is provided'with an extension I) to accommodate the receiver.
